Apple Mac OS X Samba module (SMB File Server) buffer overflow
| macos-smbfileserver-bo (32979) |  High Risk |
Description:
Apple Mac OS X is vulnerable to a stack-based buffer overflow, caused by improper bounds checking by the Samba module (SMB File Server). By persuading a victim to open a file with an overly long ACL, a remote attacker with write access to an SMB share could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
